Separating pages from one another requires fine motor skills that many may not possess

Our Solution

SLIDE 7
Our robot allows users to read a physical book without the precise motion needed to turn the page

How it works
8
SLIDE 9
For comfort and transportability, the robot is mounted
- n a lap desk
9
SLIDE 10
We utilize a wheel and flipper mechanism to turn pages, both forwards and backwards
Wheel Flipper Motor Arm
10
SLIDE 11
We utilized 3D printing to manufacture many of our components
11
SLIDE 12
The flipping action is actuated by two servos mounted on a common frame
Servo Frame 180° Servo Continuous Servo
12
SLIDE 13
To change the direction of page turning, the continuous servo can move the motor arm to either side
13
SLIDE 14
The wheel actuated by the DC motor separates a page from the rest of the book to lift it
14
SLIDE 15
The flipper arm, driven by the 180° servo, takes the raised page and flips it to the other side
15
SLIDE 16
Users can turn pages in both directions with a simple hand wave
16
SLIDE 17
Functionality
17
SLIDE 18
The individual components work together to flip any direction the user desires
18
SLIDE 19
An Arduino Uno and Adafruit motor shield work together to control the system
19
SLIDE 20
The code for the system follows this basic flow chart
20
SLIDE 21
Servo motors are coupled with ultrasonic sensors that allow for broad motions to translate into precision control

SLIDE 22
Reflection
22
SLIDE 23
Future focus on our gadget would be aimed at universalizing the page-turning mechanism and process for any book size
23
SLIDE 24
Our gadget allows people with mobility restrictions to read physical books without needing the fine motor skills to turn individual pages
